To alZ'wz/om 'it may concern:

Be it known that I, JAMES LLOYD MAO- FARLANE, a citizen of vthe United States, andl a. resident o f Atwoodville, in the county of Tolland and State of Connecticut, havev invented certain `new and useful Improve- -nients *in yTextile Machines, of which the followinY is av specification. AThis invention relates to the novel arrangement and construction of tertilespnd'les and the support thereby of 'bobbins or like devices, such as illustrated in my Patent-SNO. 1,233,591 and No. 1,233,593.

The word spindle as used in the'following description and claims refers to 'a distinctive device known by this name in the textile industry, usually supported at its lower end in suitable bearings and in upright position, though it maybe more or less inclined from vertical. The object of this invention i'sto .provide a ynovel spindle construction, and a novel bobbin support in connection therewith. 1

The drawing represents a sectional side view of aspindle made in accordance with my invention, and the bobbin holder for use therewith. Referring to the drawing, a denotes what may bek termed the base of the spindle mounted in suitable bearings b provided with a driving means, as the lbelt-receiving pulley c. d is the upper bobbin receiving portion of the spindle extending above the bearin 1 In t e baseof the spindle, or such part of the spindle as lies within limits of the bearingsv and driving mechanism, there is a longitudinal bore, 5, anda passage 6 therefrom through vthe side of the spindle above the bearings, so that a strand or thread may be passed l"from one .side of the bea-rings rid v outside 0f th`-sp11dle above the VVbearings through ihe'paissagee. Inthe ordi-` nary operation "of .a teitile machine the 'spindle is rotated; at alhighrate ofspeed, anywhere from 8,000 R. P. M. to 11,000 R. II). M, In accordance with this invention means are provided for mounting a nonrotating bobbin on the rotating spindle, and "in the embodiment of the invention illusutilized the upper end of the spindle vre-y off-setting it as at l2. Of course the base 11,

ofthe holder vfits loosely in the, recess glfO,

i and, in 'thee'mbodiment showmjthe wei' ht of the bobbin in connectiony with'tle o" A'set assists in holding the bobbin and its holder against rotation vrwith the spindle. :en the particular holder; here shown i's not utilized other means may vbe provided for supporting the bobbin onthe spindle, and'i'n 'such a way that it does not rotate.

It is found that as a result of mounting this non-rotating holder in the spindle rotating at a very high speed, the holder is subject to a certain vamount Vof vibration,

ywhich it is desirable shall not be, coininunicated to vthe-bobbin ,"and in' order toel'isniilte the vibration oi the bobb'in, a somewhat delicate resilient device is' interposed jb'etween the bobbin and the holder b'ase 1 1. One means for accomplishing this result is illustrated in the drawings, and comprises a bobbin receiver 15, which isy .yieldingly mounted, on the overbalanced end of the 'base 11, as by the coil spring 16, 2O denotes a bbbin-or other equivalent device mounted on the receiver. The base 11 and the receiver 15 constitute-what I have termed the bobbin holder i in the embodiment here illustrated and provide a substantially non- 'advantage are illu'stratediiijmy above-mentioned patents, in the firstfof which a strand is threaded through tlie spn dl e' from one side of thebearings tothe other and 'joined to a strand taken from thebob- "instances where the he rein-de `sclibed. construction. and arrangement of rotating is .in-

dler and non-rotating bobhin are of, pecu Viar bin supported on thespindle.. i 1,11 l'tter ease, the arena. ,from .theieebin in unf @wail-.innedrawings, hoben 11eme-:s use einem spindle from one side of the bearings to the other.

n essential feature of this invention is the provision of means forinounting a nonrotating bobbin holder on a rotating'spindle',

and the carrying of a thread through the' bearings inside of the spindle. These features of construction make possible the performance of certain operations, suchA as twisting and spinning strands and threads in Vways which `have-not heretofore been utilized in the textile art,-and represent great savings in power and labor, andproduce a "superior product of great uniformity.

This invention vfinds its'. peculiar -utility Vfand pra( xticab'ility inv the textile industry,

' be overcometo, as great an extent as possible.

It will be observed that the r spindle bearings "arearranged at the lower part of the spindie, while' its upper part` projects above the bearings and is free and unsupported. Also, that the bobbin holder finds its sole-support inthe location of tliebase in the recess in the upper end of the spindle, providing all the y'essential characteristics of the mechanism adapted to the' "textile industry. f

` t A conventional forml of flier, 25,`is .shown as secured to the upper end of the spindle, andlby means'of` which the thread passing through the lower portion of the spindle is manipulated. In accordance with the provisions of the patent statutes, f[ have described'the principle of operation of my invention, together with Vthe apparatus which I now consider to represent the best `embodiment thereof; but
